send post variables to my Api - ios

Question

I am trying to send post parameters to my API, it gets 4 variables :
labelled
id_produit
id_magasin
Prix
Here's my code:
#IBAction func AddProduct(sender: AnyObject) {
let myUrl = NSURL(string: "http://vps43623.ovh.net/yamoinscher/api/products/create_product");let request = NSMutableURLRequest(URL:myUrl!);
request.HTTPMethod = "POST";
// Compose a query string
let postString = "id=123456789&libelle=Florida&id_magasin=1&prix=1500";
request.HTTPBody = postString.dataUsingEncoding(NSUTF8StringEncoding);
let task = NSURLSession.sharedSession().dataTaskWithRequest(request) {
data, response, error in
if error != nil
{
print("error=\(error)")
return
}
// print out response object
print("response = \(response)")
// Print out response body
let responseString = NSString(data: data!, encoding: NSUTF8StringEncoding)
print("responseString = \(responseString)")
}
task.resume()
}
And when I execute this code I get this response:
response = Optional(<NSHTTPURLResponse: 0x7fadeaf532a0> { URL: http://vps43623.ovh.net/yamoinscher/api/products/create_product } { status code: 200, headers {
Connection = "keep-alive";
"Content-Length" = 0;
"Content-Type" = "application/x-www-form-urlencoded";
Date = "Thu, 28 Apr 2016 09:15:09 GMT";
"MS-Author-Via" = DAV;
Server = nginx;
"X-Powered-By" = PleskLin;
} })
responseString = Optional()
The console tells me that there is no variables sent to the api. Can any one help me please?

Your response is in your data object. so, convert that data in approriate response format. Ask your web service provider that your response format is string, if yes then your code seems to be right but if your response is in json format then you should convert your data in json object with jsonserialization. so check this, because your status code is 200 means ok. so,there is no problem in code i think except response serialization. Try to convert data in json or try to convert it in string with different reading option which one is appropriate.
hope this will help :)
